ELMER TOVNSEND, OF BOSTON, MASSACHUSETTS,

PEGGING-MACHINE.

Specification of Letters Patent No.

To all whom fit may concern:

Be it known that I, ELMER TowNsEND, of Boston, in the county of Suffolkand State of Massachusetts, have invented certain new and usefulImprovements in Boot and Shoe Pegging Machines, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, making part of this specification, in which-Figure l, is a perspective view of the peg feed to be attached t0 apegging machine, with my improvements connected therewith; Fig. 2, aview of the same from the opposite side; Figs. 3, 4, 5 and 6, details tobe referred to hereafter.

In boot and shoe pegging machines where a blank or strip of pegwood hasbeen fed into the machine, from which blank the pegs were cut asrequired by the machine itself, it has been heretofore customary tobevel or cha-mfer one edge of the blank as at a, Fig. 5, before it wasplaced in the machine; this adds materially to the cost of production ofthe blank, and where the blank is made, as has been, on a long coil bycutting a strip or ribbon around the log, this chamfering is liable tobreak the coil into many pieces, making it less convenient to feed intothe pegging machine. This I have obviated by beveling or chamfering theblankwhile it is beino fed into the pegging machine, by means o suitablecutters placed in proximity to the feed apparatus. For some kinds ofwork it is desirable to have the point of the peg beveled in bothdirections thus bringing it more nearly to a point. This I accomplish byarranging in the pegging machine cutting tools which operate on eachside of the edge of the blank, to form notches in it. These two devicesmay be employed in conjunction with each other, and with a feedapparatus, to bring the peg to a point; or either may be used inconjunction with the feed, and without the other. This preparation ofthe blank in the pegging machine to give the required point to the pegbefore splitting it from the blank, constitutes the first part of myinvention.

The second part of my invention consists in an improved method ofcutting the pegs from the blank, as they are used in the machine.

That others skilled in the art may understand and use my invention, Iwill proceed 27,085, dated February 7, 1860.

to describe the manner in which I have earried out the same.

In the said drawings the feed and parts which relate to my presentimprovements are detached from the pegging machine, and are driven byhand by means of a crank A, to show their operation. The crank A, isattached to and operates a shaft B, supported in suitable bearings instandards O, D, rising from the bed E.

Z) b', are two feed rolls geared together by cog wheels c. To one ofthem is attached a ratchet wheel cl, which is fed, one notch at eachrevolution of the shaft B, by a dog c, on the end of a lever F, pivotedat 3 to an arm f, attached to the standard C,-the upper end of thislever is formed in a cam 4 against which a pin z', on the shaft Bstrikes and vibrates the lever,- a spring g, holds the dog e, in contactwith the wheel (l, and a spring n, retracts the lever F. A retainingpawl z., also engages with this ratchet wheel cl. Thus at eachrevolution of the shaft B, the blank of peg wood G, is fed forward bythe rolls Z), Z9 an amount equal to the thickness of a peg. The roll b,has its bearings in two plates 7c, and the roll D in a` strap Z, whichis pressed toward the roll b, by a spring m. This allows the rolls tospring apa-rt a little to accommodate themselves to differentthicknesses of blank.

Immediately behind the feed rolls are placed two cutters lo (detached inFig. 4) which pass through the top plate lc and are secured in aninclined position by screws 5. The points of these cutters are placednear each other as shown on Fig. 4, so that their cutting edges 6 willoperate on the lower edge of the blank G, as it is pressed against themby the feed rolls I), b and bevel or chamfer it as at a Fig. 5.

A box or block II, attached to the front of the standard I) has cut init inclined ways or grooves in which slide the tools r (detached in'Fig.3); these lower ends ground to a V shaped edge as at 8, Fig. 3, and arebrought down on each side of the blank G so that they strike it at ornear the top of the bevel a (Fig. 5) and as they complete their descentcut out from each side a notch as shown at 7 Fig. 5, this notch inconjunction with the bevel a, completing the point of the peg when it issplit off froln the blank as at s, Fig. l. These tools r are operated inthe following tools ha ve theiristv manner: A pin 9 in the top of eachtool entersY an inclined slot in the end of ahori- Zontal bar I attachedto a vertical bar 29, which slides up and down in a recess in the blockH, and between two pins l() in the face of the standard D. An eccentricu on the shaft B, turns in the head of a pitman g, the other end ofwhich is pivoted at 11, to the bar p, so that at each revolution of theshaft B the tools 'l' are depressed and their points are broughttogether to form the notches 7. This is done whilst the blank Gr isstationary. These notching tools 1", may be used in conjunction with.the beveling cutters o, when it is desired to bring the peg to a pointwhen it is split from the blank as shown enlarged at w, Fig. 6, orthebeveling cutters 0, may be used alone when the point of the peg willbe sharpened ontwo of its sides only as at as, Fig. 6, or the tools `1"may beused without the cutters 0, when the point vof the peg will beformed as at 1, Fig, beveled on all four sides. In some kinds of Workand with some kindsof peg wood it will not be necessary to bring the pegto sofperfect a point as shown at w, as it will drive very well whenbeveled on two sides only.

I will now proceed to describe the second part of my invention whichrelates to separating the pegs from the blank G. It has been customaryto split the peg `from the blank in the machine immediately beforedriving the peg, by means of va simple knife attached to somereciprocating part of the machinery, which knife entered and cut throughfrom one vside of the blank to the other. This operation rather split 0Hthan cut the peg from the blank, often leaving the edge of the pegononeside rough with small splinters of the wood attached, whilst it isdesirable that the edges of the peg should be smooth, that they may bedrivenwithout tearing the sides of the hole made in the leather by theawl.

Again referring to the drawings, aV crank J, on the end of the .shaft B,is connected by a rod t to a gate K'which slides up and down in dovetailways L, attached by screws 12 to the back of the standard D. The gate K,has a recess cut in its lower end to allow the blank G to pass throughand has attached to its face by screws 13, two thin steel plates N, thecutting edges 14 of which are inclined as shown in Fig. l, so that asthe gate K descends over the end of the blank G which is protrudedkthrough bythe feed rolls, the inclinedfedges of the plates or knives N,enter from both sides of the blank andgradually c ut through it,separating-,the hpegsfFig. l from the blank and leaving its edgeson allsides smooth andin afit condition for driving. Another advantage inthis'manner of separating the pegs is, that I can employ a thinnercutting edge as it is not required to penetrate the wood to so great adepth and does not bruise and distort one side of the peg more than theother, as would be the case withi a knife which passed through from oneside to the other of the blank.y

VThe positions as well as the manner of operating the above describedtools for .pointing the peg and splitting it from` the blanks inr thepegging machine, will be variedto suit the machine to which they areapplied; I do not therefore limit myself to their arrangement orcombination one with 'the other, nor do I limit myself to Atheparticular method above described for feeding the blank as there areother wellknown ways of doing this, whichneed' not be here described.'

What I claim as my. invention Yand desire to secure by Let-ters Patentisl. Pointing the e0* on the peffoingmachine.substantially10a;described.,:iJU
